摘要
利用K型高温热电偶测试了自燃钼镍矿矿渣不同深度的温度,基于反距离权重法(IDW)和统计学方法分别绘制了不同深度温度平面分布图及竖向温度曲线,分析了水平及竖向温度分布特征,查明了高温区分布及自燃趋势性最大的区域,初步确定了火源中心;建立了竖向温度一元三次函数拟合模型,根据相关系数、方差分析及测量误差理论,确定了研究区竖向温度最优拟合模型,采用ZK5实测温度值进行了验证。以上研究结果为研究区自燃钼镍矿矿渣的修复治理提供了技术依据。
The temperature of spontaneous combustion molybdenum-nickel slag at different depths was measured by Ktype high temperature thermocouple.Based on IDW and statistical methods,the plane and vertical temperature curves of temperature at different depths were drawn respectively.The horizontal and vertical temperature distribution characteristics were analyzed,and the high temperature distribution and the largest spontaneous combustion trend area were identified.Based on the correlation coefficient,analysis of variance and measurement error theory,the optimal fitting model of vertical temperature in the study area was established,and verified by the measured temperature of ZK5.The above results provide a technical basis for the remediation of moly nickel slag in the study area.
